OK, so the "Space Jam" sequel isn't actually in the cards, but we are going to see LeBron James on the silver screen in something in the near future — the slated-for-2015-release comedy "Trainwreck," according to Mike Fleming Jr. of Deadline:

This comes after Universal bought a pic about the formative years of James and his high school teammates that will be scripted by Frank E. Flowers, with Rachel Winter and Terence Winter producing with James and his manager, Maverick Carter. As if that wasn’t enough, James, who just moved from CAA to WME, had been expected to make his feature starring debut opposite Kevin Hart in the Universal/Imagine Entertainment film Ballers.

That project has been in development for quite a while, and reportedly re-entered production in late 2013. It doesn't have an expected release date yet.
